DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors and executive officers, among others, to file with the SEC an initial report of ownership of our stock on Form 3 and reports of changes in ownership on Form 4 or Form 5. Individuals subject to Section 16 are required by SEC regulations to furnish us with copies of all Section 16(a) forms that they file. As a matter of practice, our administrative staff assists our executive officers and directors in preparing initial ownership reports and reporting ownership changes, and typically files those reports on their behalf. Based solely on a review of the copies of such forms in our possession and on written representations from reporting individuals, we believe that all of our officers and directors filed the required reports on a timely basis under Section 16(a) for fiscal year ended December 31, 2020, except for Dr. Geoffrey Guy who had one late Section 16(a) filing, which reported eleven transactions, due to an administrative error.

CODE OF BUSINESS CONDUCT AND ETHICS POLICY

Our Code of Business Conduct and Ethics is applicable to our Directors, Executive Officers, and all other employees. A copy of the code is available to every employee on our internet site, upon request to our human resources department, and to investors and others on our website at http://www.gwpharm.com or by contacting our investor relations department or legal department. Disclosure regarding any amendments to, or waivers from, provisions of the Code of Conduct that apply to our directors, principal executive and financial officers will be included in a Current Report on

Form 8-K within

four business days following the date of the amendment or waiver, unless website posting or the issuance of a press release of such amendments or waivers is then permitted by the rules of Nasdaq.

AUDIT COMMITTEE AND AUDIT COMMITTEE FINANCIAL EXPERT

Our Board of Directors has a separately designated Audit Committee. At the end of 2020, the members of the Audit Committee were James Noble (Chair), David Gryska and Dr. Catherine Mackey. Mr. Lynch passed away on April 2, 2020. Mr. Gryska joined the Company in September 2020.

The Audit Committee held eight (8) meetings and took no actions by written consent during the twelve (12) months ended December 31, 2020. The duties and responsibilities of the Audit Committee are set forth in the Terms of Reference (“Audit Committee Terms of Reference”) of the Audit Committee which was recently reviewed by our Audit Committee. Our Audit Committee determined that no revisions needed to be made to the Audit Committee at this time. A copy of the Audit Committee Terms of Reference is available on our website, located at www.gwpharm.com. Among other things, the duties and responsibilities of the Audit Committee include reviewing and monitoring our financial statements and internal accounting procedures, the selection of our independent registered public accounting firm and consulting with and reviewing the services provided by our independent registered public accounting firm. Our Audit Committee has sole discretion over the retention, compensation, evaluation and oversight of our independent registered public accounting firm.

The SEC and Nasdaq have established rules and regulations regarding the composition of audit committees and the qualifications of audit committee members. Our Board of Directors has examined the composition of our Audit Committee and the qualifications of our Audit Committee members in light of the current rules and regulations governing audit committees. Based upon this examination, our Board of Directors has determined that each member of our Audit Committee is independent and is otherwise qualified to be a member of our Audit Committee in accordance with the rules of the SEC and Nasdaq.

Additionally, the SEC requires that at least one member of the Audit Committee have a “heightened” level of financial and accounting sophistication. Such a person is known as the “audit committee financial expert” under the SEC’s rules. Our Board of Directors has determined that Mr. Noble is an “audit committee financial expert,” as the SEC defines that term, and is an independent member of our Board of Directors and our Audit Committee.

The Remuneration Committee sets up the Company’s Remuneration Policy which is designed to ensure that Directors and Executive Officers are appropriately incentivized and rewarded for their performance, responsibility and experience. The Remuneration Committee aims to ensure that the Remuneration Policy aligns the interests of Directors and Executive Officers with those of shareholders. The Remuneration Policy is designed to be competitive but aligned with accepted market practice in the United States. We consider that these design features are pivotal to our ability to offer competitive incentive packages in the markets that we compete and operate in.

During the year, the Remuneration Committee retained Anderson Pay Consultants from January 2020 to July 2020 and Aon Radford from July 2020 to present to provide ongoing peer group remuneration competitive market analysis, option valuations and remuneration policy-related advice.

Remuneration Approach

Our Remuneration Policy for Executive Directors and Executive Officers aims to:

•

align the interests of Executive Directors and Executive Officers with those of shareholders;

•

have regard to the individuals’ experience and the nature and complexity of their work in order to pay a competitive salary that attracts and retains management of the highest quality, while avoiding remunerating those Executive Directors and Executive Officers more than is necessary;

•

link individual remuneration packages to our short-term and long-term performance through the award of incentives via participation in our cash and equity-based incentive schemes;

•

provide post-retirement benefits through defined contribution pension schemes; and

•

provide employment-related benefits, including the provision of life assurance and medical assurance.

We believe that these aims, which remain unchanged from previous years, have been working well, continue to be relevant and provide a firm framework within which future remuneration will be determined. The shareholder approved Remuneration Policy provides a set of parameters within which we work while still allowing the Remuneration Committee sufficient flexibility to adapt remuneration packages in line with the development of the business. This allows the Company to attract, retain and motivate Directors and Executive Officers with the skills, talent and motivation to deliver upon our strategy and to continue to create value for our shareholders.

Key Remuneration Committee Activities during the Twelve Months Ended December 31, 2020

During 2020 the Remuneration Committee’s key activities have been as follows:

•

In February 2020, the Remuneration Committee met to consider the basic salary increases to be awarded to Executive Directors and Executive Officers. Inflationary increases had been given to the majority of our staff and the Executive Directors and Executive Officers were given an inflationary basic salary increase of 3% effective from January 1, 2020. External benchmarking analysis for the Chief Financial Officer, and Chief Operating Officer were below the median of peer group data. The Remuneration Committee approved an increase in the Chief Financial Officer’s basic salary by 5.1% to $433,000, and an increase in the Chief Operating Officer’s basic salary by 8.1% to £320,000 effective from March 1, 2020.

•

At the same time, the Remuneration Committee met to consider the extent of achievement of 2019 calendar year objectives by the Executive Team, and to determine the level of short-term bonus incentive award to be paid in respect of the 2019 calendar year. The consensus was that 2019 had been a very strong year for the Company, with strong sales of Epidiolex for the first full year in the United States and the achievement of an EMA approval for Epidyolex in Europe.

Under the bonus program, bonus incentive awards were determined by first establishing a bonus pool. The bonus pool was calculated by aggregating the target cash incentive awards for all eligible plan participants and then multiplying that sum by a modifier established by our Remuneration Committee based on our performance as measured against the 2019 company goals. The 2019 company goals approved by our Board of Directors and Remuneration Committee at the beginning of the year were as follows:

2019 Company Goals:

•

Successful U.S. Commercial trajectory of Epidiolex

•

Epidyolex approval by EMA leading to launches in major markets

•

Manufacturing

scale-up

to meet

in-market

demand for medium-term capacity requirements

•

Epidiolex label expansion by completion of Tuberous Sclerosis study to enable sNDA filing and commencement of Rett syndrome study

•

Progress with development of Epidiolex life cycle management

•

Pipeline progress with a focus on Nabiximols (Sativex)

The bonus pool was then allocated among all of the plan participants in accordance with the terms of the 2019 annual bonus incentive program. Consistent with 2018, our Chief Executive Officer and executive team bonus incentive awards were based 75% on company goals and 25% on individual objectives.

Our Remuneration Committee assessed performance and determined that the executive team had met or exceeded each of the 2019 Company goals and, after considering the success of Epidiolex commercialization in the United States, approved a bonus award equating to 115% of target for each Director or Executive Officer.

The Remuneration Committee considered that the Chief Operating Officer deserved additional recognition in respect of his individual effort towards the European approval of Epidyolex, the establishment of a European commercial organization and the manufacturing expansion projects. The Committee approved an incremental bonus award taking total bonus to 120% of target.

•

At the same time, the Remuneration Committee approved the bonus objectives to be achieved by the Executive Directors during 2020. Bonus targets were agreed at 70% of basic salary for the Chief Executive Officer, and 50% of basic salary for all other Executive Officers. Consistent with previous years, individual objectives were agreed with each of the Executive Team, with 75% of the 2020 bonus award based upon achievement of Group objectives and the remaining 25% awarded based upon the achievement of individual objectives.

•

At the same time, the Remuneration Committee met and agreed the terms of the 2020 grant of LTIP awards to the Directors and Executive Officers. These were segmented so that (i) 50% of the value of the award is linked to rigorous performance conditions linked to Company key value drivers, which must be achieved in the three-year vesting period and (iii) 25% of the value of the award took the form of restricted share options which vest at the rate of 25% per annum over a four-year vesting period.

Recommendations for equity grants had been proposed by Andersen Advisors, designed to target alignment with the median of peer group data. At the grant date these awards had expected values at grant equivalent to 750% of basic salary for the Chief Executive Officer, 450% of basic salary for the Executive Chairman, 350% of basic salary for Chief Financial Officer, Chief Legal Officer and Chief Operating Officer, Chief Medical Officer, and Managing Director, U.K.

•

In July 2020 Aon Radford were engaged as independent advisors to the Remuneration Committee.

•

In September 2020 Aon Radford was asked to review current provisions and market practice for involuntary termination in the event of a Change in Control and in the absence of an event of a Change in Control. These findings were presented to the Remuneration Committee in January 2021.

•

In December 2020 our independent advisor, Aon Radford, performed a benchmarking exercise on the remuneration of the Directors against the selected peer group and provided recommendations for basic salaries, Long Term Incentive Plan (“LTIP”) awards,

new-hire

equity awards, prevalence of performance plans and the structure of bonus incentive awards for the year. As the Company continues to grow in size and complexity, the Remuneration Committee requested that Aon Radford review the peer group of comparable U.S.-listed biotech/pharmaceutical development companies.

Aon Radford suggested biopharmaceutical companies with a focus on neurology, orphan, or rare diseases where possible and that have commercialized medicines to reflect GW’s current stage of development. In addition, these companies have a market capitalization generally between $1.0 billion to $9.5 billion, revenues of $100 million to $1.3 billion in revenue and 300 to 3,000 employees. This resulted in a shortlist of organizations considered to be close competitor which was then subject to review, refinement and approval by the Remuneration Committee.

Based on these criteria Aon Radford recommended, and our Committee approved, the latest peer group consisting of 21 companies. The peer group used for benchmarking consisted of:

ACADIA Pharmaceuticals, Inc., Agios Pharmaceuticals, Inc., Alkermes plc, Amarin Corporation plc, Amicus Therapeutics, Arena Pharmaceuticals, bluebird bio, Inc., Corcept Therapeutics Inc, Exelixis, Inc., Halozyme Therapeutics, Inc., Insmed, Intercept Pharmaceuticals Inc., Ionis Pharmaceuticals, Neurocrine Biosciences Inc., Pacira Biosciences, PTC Therapeutics, Sage Therapeutics, Inc., Sarepta Therapeutics, Inc., Supemus Pharmaceuticals, Ultragenyx Pharmaceuticals, Inc. and United Therapeutics Corporation.

•

In January 2021, the Remuneration Committee met to consider the basic salary increases to be awarded to Executive Officers. Inflationary increases had been given to the majority of our staff and the Executive Directors were given an inflationary basic salary increase of 3% effective from January 1, 2021.

•

At the same time, the Remuneration Committee met to consider the extent of achievement of 2020 calendar year objectives by the Executive Team, and to determine the level of short-term bonus incentive award to be paid in respect of the 2020 calendar year. The consensus was that 2020 had been a strong year for the Group, with strong sales of Epidiolex in the United States, the launch of Epidyolex in European markets. Employee engagement reached an

all-time

high in this period at 89.6%, manufacturing productivity also improved and all supply challenges were met successfully. This all against the backdrop of the COVID pandemic which proved challenging conditions for both clinical trials and face to face interactions with HCPs by sales representatives.

Under the bonus program, bonus incentive awards were determined by first establishing a bonus pool. The bonus pool was calculated by aggregating the target cash incentive awards for all eligible plan participants and then multiplying that sum by a modifier based on our performance as measured against the 2020 company goals. The 2020 company goals approved by our Board of Directors and Remuneration Committee at the beginning of the year were as follows:

2020 Company Goals:

•

Innovate Drug Discovery

•

Expand Product Development

•

Deliver Commercial Success

•

Evolve the Organization

•

Shape the External Environment

The bonus pool was then allocated among all of the plan participants in accordance with the terms of the 2020 annual bonus incentive program. Consistent with 2019, our Chief Executive Officer and executive team bonus incentive awards were based 75% on company goals and 25% on individual objectives.

Our Remuneration Committee assessed performance and determined that the executive team had met or exceeded each of the 2020 Company goals and, after considering the success of Epidiolex sales in the US and the successful launch of Epidyolex in Europe, the FDA TSC approval, and on track for all R&D goals with the exception of those impacted by COVID, the Remuneration Committee approved a bonus award equating to 110% of target for each Director or Executive Officer.

Bonus targets are 70% of basic salary for the Chief Executive Officer, and 50% of basic salary for all other Executive Officers. Consistent with previous years, individual objectives have been agreed with each of the Executive Team, with 75% of the 2020 bonus award to be awarded by the Remuneration Committee based upon achievement of Group objectives, with the remaining 25% to be awarded based upon the achievement of individual objectives.

•

At the same time, the Remuneration Committee met and agreed the terms of the 2021 grant of LTIP awards to Directors and Executive Officers. These were segmented so that (i) 50% of the value of the award is linked to rigorous performance conditions linked to Company key value drivers, which must be achieved in the three-year vesting period, (ii) 50% of the value of the award took the form of restricted share options which vest at 25% per annum over a four-year vesting period.

The selected performance conditions that are required to be achieved in order to trigger vesting of 50% of this award are again considered to be directly linked to key business value drivers creating alignment with shareholders’ interests. The restricted share option element of the award is considered to encourage long-term retention, considered to be a key factor critical to future success, and the market priced options are intended to align further the interests of the Executive Directors with shareholders’ interests. The resulting mix is designed

to create an appropriate balance of long-term incentives linked to value-driving objectives, aligned with shareholder value creation, whilst encouraging retention of the team considered to be a key success factor for the future.

Recommendations for Total Direct Compensation was proposed by Aon Radford, designed to target alignment with the median of peer group data. It was highlighted that an equity grant for the Chief Executive Officer equivalent to 850% of basic salary is required to align with the 50

percentile of peers. Aon Radford also recommended that the Executive Chairman’s Total Direct Compensation should not exceed

60-–65%

of CEO Total Direct Compensation. The Remuneration Committee therefore approved an equity grant for the Executive Chair bringing his Total Direct Compensation to 50% of the CEO’s. At the grant date these awards had expected values at grant equivalent to 490% of basic salary for the Executive Chairman, 350% of basic salary for Chief Financial Officer, Chief Legal Officer and Chief Operating Officer, Chief Medical Officer, and Chief Commercial officer (US).

The Remuneration Policy was approved by shareholders at the June 2019 Annual General Meeting and we will not be seeking a review of this policy until the planned review date in 2022.

Roles in Determining Compensation

Remuneration Committee

In accordance with best practice, the Remuneration Committee, consisting of independent

non-executive

Directors, manages the remuneration of the Executive Directors within the framework of the shareholder approved Remuneration Policy and shareholder approved LTIP option scheme rules.

Remuneration Committee Interlocks and Insider Participation

No member of the Remuneration Committee during fiscal year 2020 was an employee or former employee of the Company. During fiscal year 2020, none of our executive officers served on the compensation committee (or its equivalent) or board of directors of another entity where one of our Committee members was an executive officer, and no Committee member had a relationship requiring disclosure under Item 404 of Regulation

S-K

Risks Related to Compensation Policies and Practices

As part of the Board of Director’s risk oversight role, our Remuneration Committee reviews and evaluates the risks associated with our compensation programs. Our Remuneration Committee has reviewed our compensation policies as generally applicable to our employees and believes that our policies do not encourage excessive and unnecessary risk-taking, and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on the Company. In making this determination, our Remuneration Committee considered the following:

•

the Company’s use of different types of compensation vehicles to provide a balance of long- and short- term incentives with fixed and variable components;

•

the granting of equity-based awards with time-based vesting and performance-based vesting, both of which encourage participants to work towards long-term appreciation in equity values;

•

the Company’s annual bonus determinations for each employee and vesting of performance-based equity awards being tied to achievement of Company goals, which goals promote long-term value; and

•

the Company’s system of internal control over financial reporting and code of conduct and ethics, which, among other things, reduce the likelihood of manipulation of the Company’s financial performance to enhance payments under any of its incentive plans.

Compensation Consultant

The Remuneration Committee retained the following as independent external compensation consultants: Anderson Pay Advisors from January 2020 to July 2020 and Aon Radford from July 2020 to present. The mandate of the consultants includes assisting the Remuneration Committee in its review of executive and director compensation practices, including the competitiveness of pay levels, executive compensation design, and competitive market analysis with the Company’s peers in the industry. The Remuneration Committee regularly evaluates the performance of its compensation consultants, considers alternative compensation consultants, and has the final authority to engage and terminate such services.

Chief Executive Officer

Our Chief Executive Officer attends Remuneration Committee meetings and works with the Remuneration Committee Chairman and its compensation consultants to develop compensation recommendations for Executive Officers (excluding the Chief Executive Officer) and other key executives, based upon individual experience and breadth of knowledge, internal considerations, individual performance during the fiscal year, and other factors deemed relevant by the Remuneration Committee. The recommendations are then submitted to the Remuneration Committee for review and consideration. The Remuneration Committee works directly with its compensation consultants to determine compensation actions for the Chief Executive Officer. In accordance with Nasdaq listing rules, our Chief Executive Officer is not present during voting or deliberations concerning his own compensation.

Say-on-Pay

In accordance with the requirements of Companies Act 2006, as a U.K. resident company listed on a recognized stock exchange, we are required to establish a Directors’ Remuneration Policy, containing a framework of limits within which the Remuneration Committee are authorized by shareholders to operate. This is required to be approved by shareholders at least every three years, by the passing of an ordinary resolution at the annual general meeting of shareholders. Additionally, annually at our general meeting of shareholders (“AGM”), we hold a

non-binding

advisory vote required by Section 14A of the Securities Exchange Act of 1934, as amended regarding the compensation of our named Executive Officers.

At the AGM in May 2020, 99% of shareholders approved the 2019 Remuneration Report. At the same meeting, 99% of shareholders voted to approve, on a

non-binding

advisory basis, the compensation of the Company’s named executive officers. The Directors’ Remuneration Policy was last approved at AGM in June 2019, and is therefore not due for shareholder reapproval until 2022. In the event that we experience significant levels of shareholder votes against any remuneration-related resolutions we will seek to investigate the reasons for such votes and in the event that the Remuneration Committee consider that changes to the Remuneration Policy are appropriate, we will disclose details of proposed changes in a timely manner.

The Remuneration Committee has considered and will continue to consider the outcome of such votes when making future compensation decisions for our named Executive Officers. The Remuneration Committee believes that the most relevant period of time to assess the performance of the Company’s Chief Executive Officer is the period since our Nasdaq listing, which commenced in May 2013, during which the Company’s ADS price significantly outperformed both its peer group and the Nasdaq Biotechnology Index as a whole. The Remuneration Committee also relies on advice from its compensation consultant, its evaluation of Company performance against

pre-defined

corporate goals, its understanding of the challenges facing the Company and its observations of executive officer performance to determine executive officer compensation.

Competitive Market Analysis

The Remuneration Committee draws on a number of resources to assist in the evaluation of the various components of the Company’s executive compensation program. While we do not establish compensation levels based solely on competitive market analysis, pay practices at other companies are a factor that the Remuneration Committee considers in assessing the reasonableness of compensation and ensuring that our compensation practices are competitive in the marketplace.

Our peer companies used in determining compensation actions with respect to 2020 compensation were selected by the Remuneration Committee with the support of Anderson Pay Consultants from January 2020 to July 2020 and Aon Radford, which, since July 2020, has been retained to conduct comprehensive reviews of the Company’s executive compensation practices.

The Remuneration Committee considered the foregoing analysis in selecting the following 21 peer companies for use in evaluating compensation actions during 2020:

The Remuneration Committee reviews the Company’s list of peer companies on an annual basis to reflect changes in market capitalization, acquisitions, developments at the Company relative to its peer companies, and other factors.

Components of Compensation and Target

Executive Directors’ and Executive Officers’ remuneration packages are considered annually and for the twelve (12) months ended December 31, 2020 comprised a number of elements, as follows:

(i)

Fixed Elements of Remuneration

Fixed elements of remuneration including basic salary, pension contributions and other benefits will be set and paid in accordance with our Remuneration Policy. Any changes to salary will be considered in the context of a number of factors including the annual peer Group based benchmarking exercise carried out by Aon Radford for the Remuneration Committee, home-market location, any changes to executive responsibilities since the last review and broader employee increases.

(ii)

Short-Term Incentive

The Remuneration Committee met in January 2021 to assess Director and Executive Officer performance for the calendar year ended December 31, 2020. Based upon this assessment and in accordance with the Remuneration Policy Report below, the Remuneration Committee awarded a cash bonus payment to each Executive Director and Executive Officer.

(iii)

Long-Term Incentive Plan

Equity grants under the Long-Term Incentive Plan in 2021 are comprised of two elements:

•

Performance restricted share units

, whereby the options will vest upon the third anniversary of the date of grant subject to certain corporate performance conditions having been achieved.

•

Restricted share options (or restricted share units for U.S.-based Directors or Executive Officers),

whereby these options are subject to a four-year service condition and vesting period. 25% of the options will vest on each anniversary of the date of grant over the next four years.

It is the Committee’s expectation that, unless a Director or Executive Officer no longer remains in such position when the service period has completed, that all market-price and restricted share options will vest. This would be applicable to any options where vesting is scheduled to complete during 2021.

The performance share option element of the February 2018 LTIP award vested on February 26, 2021. 50% of the overall awards were in the form of performance share options, with a corporate performance condition:

•

50% vest upon the approval of Epidiolex by the US FDA.

•

50% vest upon the launch of Epidiolex in the United States.

100% of the 2018 LTIP award vested on February 26, 2021.

Future Policy Table

The policy table below describes GW’s shareholder-approved Remuneration Policy for Executive Directors and Executive Officers and seeks to explain how each element of the Executive Directors’ and Executive Officers’ remuneration packages operates:


Element of remuneration	Purpose and link to strategy	Operation	Changes to be proposed	Maximum	Performance targets

Salary	Rewards skills and experience and provides the basis for a competitive remuneration package	Salaries will be reviewed annually by reference to market practice and market data, on which the committee receives independent advice, rates of inflation, broader employee increases, the individual’s experience and scope of the role. Salaries will be benchmarked against comparable roles in a selected peer group of other US-listed pharmaceutical development companies with similar market capitalizations and/or scale of operational complexity. We typically expect to align salaries with the 50th percentile of peer group comparator data but may vary from this general rule where we consider that special circumstances apply or where recruitment or retention of a particular role is required. The Committee may also decide to approve future increases following changes to job responsibilities or to reflect experience within the role	None	Salaries will not exceed the 75th percentile of peer group comparator data for the relevant role. The committee will reference alternative comparator data for roles not widely represented in the core peer group.	Not applicable

Retirement savings plan	Enables Executive Directors and Executive Officers to build long-term retirement savings	Company contribution to a personal pension/401(k) scheme or salary supplement. Levels will be reviewed annually, and the committee may decide to increase future contribution levels should the review indicate such a change is appropriate. Statutory limits to employer contributions will be applied	None	Up to 5% of basic salary	Not applicable


Element of remuneration	Purpose and link to strategy	Operation	Changes to be proposed	Maximum	Performance targets

Benefits	Protects against risks and provides other benefits in line with market practice	Benefits currently include death-in-service life insurance, family private medical cover, ill-health income protection and a taxed cash car allowance. The committee will review benefits offered from time to time and retains the discretion to add or substitute benefits to ensure they remain market competitive. In the event that the Group requires an Executive Director or Executive Officer to relocate, we would offer appropriate relocation assistance and would be likely to update the package of benefits to align with local market practice, e.g. increased health insurance benefits if relocating to US.	None	The disclosed taxable value of benefits and allowances is not expected to exceed 15% of salary per annum. The Committee may exceed this in the event of relocation, both on a one-off and ongoing basis to align with local market norms.	Not applicable


Element of remuneration	Purpose and link to strategy	Operation	Changes to be proposed	Maximum	Performance targets

Short-term incentive awards	Incentivizes and rewards achievement of the near-term business objectives, reflecting individual and team performance of the Executive Directors and Executive Officers	Objectives are set at the start of each calendar year. The choice of annual performance objectives will reflect the committee’s assessment of the key milestones/metrics required to be achieved within the calendar year in order to make progress towards achieving GW’s strategic plan. Payable in cash. Clawback provisions will apply (see details below).	None	Up to 150% of salary	The Committee retains the ability to set performance objectives annually. These objectives can be Group-based and/or individual, financial and/or non-financial, and are likely to include various milestones linked to: • successful execution of key elements of the Epidiolex ® development program and worldwide commercialization; • identification and execution of other new orphan drug developments; • key regulatory steps (IND grants, NDA filings, regulatory approvals); • successful commercialization of approved products, either by our own commercial organization or by our partners; • the Group’s financial position and results; and • equity liquidity and valuation

Conditional awards of nominal- cost options, share options, performance shares and/or restricted shares. Awards normally vest over periods of three or more years. The committee is able to grant awards which permit phased vesting over the period. Clawback provisions will apply (see details below).	Individual awards in any one year will not exceed the 75 th percentile of peer group data	Individual awards in any one year will not exceed the 75 th percentile of peer group data. Expected values are calculated in accordance with generally accepted methodologies based on Black- Scholes or binomial stochastic models.	Performance conditions are set at the discretion of the Remuneration Committee and will generally consist of a mixture of: • service requirements; • milestone-based events, linked to the successful execution of GW’s strategic plan, likely to include items such as positive trial results, or regulatory approvals; and • market-based measures such as absolute or relative share price performance Major shareholders may be consulted as part of the process of setting performance conditions.

Employment Agreements and Change in Control Arrangements

All of the Company’s listed officers are employed at will, other than Dr. Guy, with employment agreements or offer letters (subject only to the effect of local labor laws). Dr. Guy’s service agreement provides that his service will continue until either party provides no less than 12 months’ written notice. GW Research Limited may terminate Dr. Guy’s employment, with immediate effect at any time by notice in writing for certain circumstances as described in his service agreement, including bankruptcy, criminal convictions, gross misconduct or serious or repeated breaches of obligations of his service.

On February 24, 2021, Greenwich Biosciences adopted the Greenwich Biosciences Amended and Restated Change in Control and Severance Benefit Plan and participation agreements thereunder (the “U.S. Severance Plan”), which includes the Company’s U.S.-based executive officers (collectively, the “U.S. executives”) and other participants. The U.S. Severance Plan generally provides that in the event a U.S. executive’s employment terminates without cause or for good reason (each as defined in the U.S. Severance Plan) other than during the period commencing one month prior to or 24 months following a “Change in Control” of the Company (as defined in the U.S. Severance Plan), the participant would be entitled to: (i) cash severance payments equal to his or her base salary; (ii) payment of COBRA premiums for continued medical coverage for up to 12 months; and (iii) outplacement benefits for up to 6 months not to exceed $15,000. In the event a U.S. executive’s employment terminates without cause or for good reason during the period commencing one month prior to or 24 months following a Change in Control of the Company (a “qualifying termination”), he would be entitled to: (i) cash severance payments equal to the sum of his base salary and the greater of the annual target bonus for the year of termination and the average of actual annualized bonus in respect of the three most recent fiscal years, multiplied by two in the case of Mr. Gover and one and a half in the case of the other U.S. executives; (ii) payment of COBRA premiums for continued medical coverage for up to 18 months (in the case of Mr. Gover, 24 months) and (iii) outplacement benefits for up to 6 months not to exceed $15,000. In addition, the U.S. Severance Plan provides that upon a change in control of the Company, all equity awards of the Company held by such executive (other than those granted in 2021) will fully vest.

On February 24, 2021, the Company also adopted the GW UK Change in Control and Severance Benefit Plan and the participation agreements thereunder (collectively, the “U.K. Severance Plan”), which includes Geoffrey Guy, the Company’s Executive Chairman, and other participants. The U.K. Severance Plan generally provides that in the event Dr. Guy’s employment terminates without “cause” or for “good reason” (each as defined in the U.K. Severance Plan) other than during the

24-month

period following a “Change in Control” (as defined in the U.K. Severance Plan), he would be entitled to continued medical coverage for up to 12 months. In the event his employment terminates without “cause” or for “good reason” within 24 months following a Change in Control, he would be entitled to: (i) cash severance payments equal to two times his base salary; and (ii) payment of premiums for continued medical coverage for up to 24 months. In addition, the U.K. Severance Plan provides that upon a change in control of the Company, all equity awards of the Company held by Dr. Guy (other than those granted in 2021) will fully vest.

Clawback Policy

The clawback policy provides that certain incentive compensation is recoverable from a Director if the Company is required to restate financial statements due to the misconduct of that particular Director, and that misconduct has significantly contributed to the need for the restatement. Generally, eligible incentive grants shall include cash short-term incentive awards and equity-based long-term incentive awards that have been awarded and/or vested based upon achievement of specific financial or operational goals which were deemed to have been achieved but which, following restatement, are considered to no longer have been achieved. To be effective, intention to claw back awards which have already vested and been exercised must be notified to the Director within 24 months of the award having vested. The Committee may effect a clawback either through a cash or equity repayment by the individual, or via an adjustment to an outstanding award that is yet to vest or that has vested but is not yet exercised.

Equity Retention Policy

To encourage executives to retain a meaningful amount of equity in the Company, a retention policy is in effect for Directors and Executive Officers. The purpose of this policy is to encourage ownership of the Company’s shares, promote alignment of the long-term interests of the Directors and Executive Officers with those of our shareholders, and promote our commitment to sound corporate governance. The policy is applicable to our Directors and Executive Officers, and certain other members of our leadership team, as nominated by our Chief Executive Officer. Under the policy, covered Directors and officers must retain an agreed proportion of each new equity grant issued to them after January 1, 2015, subject to the payment of any applicable taxes, for a period of five years from vesting until an overall level of share ownership is achieved. The target level of ownership equates to four times basic salary for the Chief Executive Officer and two times basic salary for the other Directors and Officers. The target deadline for achieving the ownership requirement is intended to be five years from implementation of the policy. Existing shareholdings or direct purchases of equity by executives shall contribute towards attainment of the targeted shareholding cap. The committee retains the power to consider an individual ineligible for future equity incentive grants if the required target has not been achieved in a timely manner, subject to the consideration of individual circumstances.

Tax Deductibility

Prior to the Tax Cuts and Jobs Act signed into U.S. law in December 2017 (the “TCJA”), Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), generally limited the U.S. federal corporate income tax deduction for compensation paid to a corporation’s CEO and its three other most highly compensated executives (other than the CFO) to $1.0 million annually, unless certain requirements were satisfied. The TCJA contained significant changes to Section 162(m) of the Code, including the elimination of the performance-based compensation exception to Section 162(m) for corporate tax years beginning after December 31, 2017 and an expansion of employees covered by the provision. Section 162(m) now covers the CFO or any individual who served as the CFO in the relevant taxable year. In addition, once an individual becomes a “covered employee”

under Section 162(m) for any taxable year beginning after December 31, 2016, this status carries forward to all future years, even in the event of the employee’s termination or death. The TCJA provides limited transition relief for certain “performance-based” compensation, specifying that compensation payable pursuant to a written binding contract which was in effect on November 2, 2017 and which was not modified in any material respect on or after that date is “grandfathered” (i.e., remains eligible for the “performance-based” pay exception to Section 162(m) and, to the extent such exception is satisfied, such compensation remains deductible even if in excess of $1.0 million)).

We were a foreign private issuer until October 1, 2018. When we were a foreign private issuer, Section 162(m) did not apply to us. In addition, several of our executive officers who are covered employees for purposes of Section 162(m) perform their services primarily in the United Kingdom, and, as a result, our deduction for their compensation is not limited bySection 162(m). Because of these two factors, the $1.0 million compensation deduction limitation of Section 162(m) and its exception to the $1.0 million deduction limitation for performance-based compensation have not been significant considerations for us when designing and implementing our executive officers’ compensation program in prior years and will not be significant considerations in future years, and even to the extent deductibility is a consideration, it will not be the sole factor used in determining levels or methods of compensation. Since our compensation objectives may not always be consistent with the requirements for full deductibility, we and our subsidiaries may enter into compensation arrangements under which payments would not be deductible under Section 162(m).

We believe that under the TCJA transition relief for “performance-based” compensation, amounts that may become payable to our executive officers who are covered employees in respect of incentive compensation awards granted to them prior to November 2, 2017 may be grandfathered and, therefore, not subject toSection 162(m)’s $1.0 million deduction limitation. However, we will continue to evaluate whether the TCJA transition relief for “performance-based” compensation is available in light of recently issued guidance from the Internal Revenue Service and any subsequent guidance that may be issued. In addition, some of the foregoing incentive compensation that may become payable to our executive officers who are covered employees may be deductible on our United Kingdom tax return, and therefore, not limited by Section 162(m) in any event.

General Discretions Relating to the Operation of Incentive Plans

The Remuneration Committee will operate all incentive plans in accordance with LTIP rules and will retain full discretion over a number of areas relating to the operation and administration of these plans. This includes, but is not limited to, determining eligibility, setting performance conditions, determining the extent to which performance conditions are achieved, terms for leaving the Company and the vehicle of delivery.

Approach to Recruitment Remuneration

The remuneration package for a new director or executive officer, including basic salary, benefits, pension, annual bonus/short-term incentive and long-term incentive awards, will be set in accordance with the terms of the Company’s prevailing approved Remuneration Policy at the time of appointment. The Remuneration Committee will consider the role, responsibility and experience of the candidate and will seek independent advice and market data to help derive an appropriate level of remuneration in order to secure the right candidate with the required skills and experience for the role. To facilitate recruitment, the Remuneration Committee may offer additional cash and/or share-based remuneration to take account of, and compensate for, remuneration that the director is required to relinquish when leaving a former employer. Any such offer would take into account the nature, time horizon and performance conditions attached to any such remuneration and would seek to offer no more than the potential value of the remuneration opportunity being relinquished. For an internal executive director appointment, any variable pay element awarded in respect of the prior role will be allowed to pay out according to its terms. In addition, any other contractual remuneration obligations existing prior to appointment may continue. For external and internal appointments, the Remuneration Committee may agree that the Company will provide reasonable relocation support. In all cases, the Remuneration Committee will ensure that decisions made are in the best interests of the Company. The remuneration for any

non-executive

appointments will be set in accordance with

the prevailing Remuneration Policy. Typically, the first grant of equity-based incentive awards made after appointment of a new

non-executive

to the Board of Directors will be increased by 50%. No additional cash payments will usually be made.

Although the U.S. Severance Plan and U.K. Severance Plan were not in effect as of December 31, 2020, the table below applies the U.S. Severance Plan and U.K. Severance Plan approved on February 24, 2021.

(1)

The value of the accelerated vesting of options equals the difference (if positive) between the option exercise price and the closing price per share of our ADSs on December 31, 2020 ($115.41), multiplied by the number of shares that would have been accelerated upon a termination occurring on December 31, 2020.

(2)	Treatment of acceleration of options is subject to Remuneration Committee discretion. The disclosure assumes full vesting of all options.

Narrative to the 2020 Potential Payments Upon Termination or Change in Control

The amounts reported in the 2020 Potential Payments Upon Termination or Change in Control are described more fully under “Employment Agreements and Change in Control Arrangements”.

2020 Pay Ratio

Pursuant to a mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC adopted a rule requiring annual disclosure of the ratio of the median employee’s total annual compensation to the total annual compensation of the principal executive officer (“PEO”). The PEO of our Company is Justin Gover, our Chief Executive Officer.

We believe that our compensation philosophy must be consistent and internally equitable to motivate our employees to create shareholder value. The purpose of the new required disclosure is to provide a measure of pay equity within the organization. We are committed to internal pay equity, and our Remuneration Committee monitors the relationship between the pay our PEO receives and the pay our

non-executive

employees receive.

As illustrated in the table below, our PEO to median employee pay ratio for the twelve (12) months ended December 31, 2020 was approximately 48.5:1


PEO Compensation	$	6,159,400
Median Employee Compensation	$	127,006
Ratio of PEO to Median Employee Compensation		48.5:1

We identified the median employee using annualized base salary and salary allowances at December 31, 2020 and bonus potential to be earned during the twelve (12) months ended December 31, 2020. Equity awards were excluded from the calculation of determining the median employee due to the high volume of staff who had joined our Company during the twelve (12) months ended December 31, 2020. Equity awards were then added to the median employee pay to ensure comparability with the PEO.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Fees typically consist of a basic fee for non-executive Director responsibilities plus incremental fees for additional roles/ responsibilities, such as chairmanship of the Board of Directors sub-committees, senior non-executive Director and U.S. representative Director roles. Fees can be paid in the form of cash or shares to be held until the individual retires from the Board of Directors. Any element of fees paid in the form of shares will not be subject to performance conditions The non-executive Directors do not receive any pension from the Company, nor do they participate in any performance-related incentive plans. Future equity-based awards will be subject to the equity retention policy set out above.	The value of individuals’ aggregate fees will not exceed the 75th percentile of peer group comparator data.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

The following table and related footnotes set forth certain information regarding the beneficial ownership of GW ordinary shares (including GW ADSs, each of which represents 12 GW ordinary shares) as of April 23, 2021 with respect to:

•

each person known by GW to beneficially own more than 5% of the outstanding GW ordinary shares based solely on GW’s review of SEC filings;

•

each of GW’s named executive officers;

•

each of GW’s directors; and

•

all of GW’s executive officers and directors as a group.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC. Under these rules, beneficial ownership includes any shares as to which a person has sole or shared voting power or investment power. In computing the number of GW ordinary shares beneficially owned by a person and the percentage ownership of that person, GW ordinary shares subject to options, or other rights held by such person that are currently exercisable or will become exercisable within 60 days of April 23, 2021 are considered outstanding. These ordinary shares, however, are not included in the computation of the percentage ownership of any other person. Applicable percentage ownership is based on 378,407,422 GW ordinary shares outstanding as of April 23, 2021.

Unless otherwise noted below, the address of each beneficial owner listed in the table below is c/o GW Pharmaceuticals plc, Sovereign House, Vision Park, Chivers Way, Histon, Cambridge, CB24 9BZ, United Kingdom.

Item 13. Certain Relationships and Related Transactions, and Director Independence.

TRANSACTIONS WITH RELATED PERSONS

Certain Relationships and Related Party Transactions

Other than the compensation arrangements described above under the section “Compensation Discussion and Analysis,” during the twelve (12) months ended December 31, 2020 through the date of this proxy statement, we were not a party to any transactions involving an amount exceeding $120,000 between us and certain “related parties,” which are generally considered to be our Directors and Executive Officers, nominees for director, holders of 5% or more of our outstanding ordinary shares and members of their immediate families.

Approval of Related Party Transactions

We have adopted a related person transaction policy which sets forth our procedures for the identification, review, consideration and approval or ratification of related person transactions. For purposes of our policy only, a related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we and any related person are, were or will be participants. Transactions involving compensation for services provided to us as an employee or director are not covered by this policy. A related person is any employee, director or beneficial owner of more than 3% of any class of our voting securities, including any of their immediate family members and any entity owned or controlled by such persons.

Under the policy, if a transaction has been identified as a related person transaction, including any transaction that was not a related person transaction when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, our management must present information regarding the related person transaction to our Audit Committee, or, if Audit Committee approval would be inappropriate, to another independent body of our Board of Directors, for review, consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to us of the transaction and whether the transaction is on terms that are comparable to the terms available to or from, as the case may be, an unrelated third party or to or from employees generally. Under the policy, we will collect information that we deem reasonably necessary from each Director, Executive Officer and, to the extent feasible, significant shareholder to enable us to identify any existing or potential related person transactions and to effectuate the terms of the policy. In addition, under our Code of Business Conduct and Ethics, our employees and directors have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest.

Independence of our Board of Directors

We believe that the Company benefits from having a strong and independent board of directors. On an annual basis, our Board of Directors review the independence of all Directors under guidelines established by Nasdaq and in light of each director’s affiliations with the Company and members of management, as well as significant holdings of Company securities. This review considers all known relevant facts and circumstances in making an independence determination. The Board of Directors has determined that all of the Directors that currently serve on our Board of Directors are, and all of the Directors that served on the Board of Directors during the twelve (12) months ended December 31, 2020 were, independent, except for Dr. Geoffrey Guy and Justin Gover.
